Patch for line-comments

Philipp Marek — 2012-09-28T06:06:16

After a short discussion on #lisp the current behaviour was seen as a bug; a
line-comment should _only_ be terminated by a newline, and not by a terminating
character as well.

Eg. for

  #?rx( ...
        # (a test)
      hello)

the current version would return an error about "hello" being an unknown variable.


Regards,

Phil

Support for Perl $1 and Makefile-like specialvariables

Evgeniy Zhemchugov — 2009-12-16T15:00:51

Dear cl-interpol developer(s),

I would like to use cl-interpol to parse strings containing Perl
subpattern variables like $1 and Makefile special variables like $<,
$^ etc. I also want statements like #?"$(f 5)" when
*optional-delimiters-p* is t to be expanded into something like

(with-output-to-string (#:string) (princ (f 5) #:string))

rather than

(with-output-to-string (#:string) (princ (progn f 5) #:string))

as they do now. (However, for better compatibility with Makefiles I
need to treat the case of the list made of a single element in a
special way, expanding it to the value of the corresponding variable.)
Overall, I would like to have better control over the read-form
function, maybe the possibility to supply my own one. Could you
install some hook there? I'd gladly do it myself and send you a patch
but I'm not sure which way is the best and whether you will accept
such a change at all. If you advice me some workaround that doesn't
involve modifying cl-interpol it would also be great. I just don't
